Dismissal Another way of dividing a Mass is into its "ordinary" parts—those texts which, with some variations, are part of the Mass on a daily basis—and its "proper" parts—the texts of prayers and selection of Scripture readings proper to the specific feast, feria or other occasion being observed. INTRODUCTORY RITES The Mass begins with the entrance chant/song. The celebrant and other ministers enter in procession and reverence the altar with a bow and/or a kiss. The altar is a symbol of Christ at the heart of the assembly and so deserves this special reverence. All make the Sign of the Cross and the celebrant extends a greeting to the gathered people in words taken from Scripture. The Penitential Act follows the greeting. At the very beginning of the Mass, the faithful recall their sins and place their trust in God's abiding mercy. The Penitential Act includes the Kyrie Eleison, a Greek phrase meaning, "Lord, have mercy." This litany recalls God's merciful actions throughout history. On Sundays, especially in Easter Time, in place of the customary Penitential Act, from time to time the blessing and sprinkling of water to recall Baptism may take place. On Sundays, solemnities, and feasts, the Gloria follows the Penitential Act. The Gloria begins by echoing the proclamation of the angels at the birth of Christ: "Glory to God in the highest!" In this ancient hymn, the gathered assembly joins the heavenly choirs in offering praise and adoration to the Father and Jesus through the Holy Spirit. The Introductory Rites conclude with an opening prayer, called the Collect. The celebrant invites the gathered assembly to pray and, after a brief silence, proclaims the prayer of the day. The Collect gathers the prayers of all into one and disposes all to hear the Word of God in the context of the celebration. LITURGY OF THE WORD Most of the Liturgy of the Word is made up of readings from Scripture. On Sundays and solemnities, there are three Scripture readings. During most of the year, the first reading is from the Old Testament and the second reading is from one of the New Testament letters. During Easter Time, the first reading is taken from the Acts of the Apostles which tells the story of the Church in its earliest days. The last reading is always taken from one of the four Gospels. In the Liturgy of the Word, the Church feeds the people of God from the table of his Word (cf. Sacrosanctum Concilium, no. 51). The Scriptures are the word of God, written under the inspiration of the Holy Spirit. In the Scriptures, God speaks to us, leading us along the path to salvation. The Responsorial Psalm is sung between the readings. The psalm helps us to meditate on the word of God. The high point of the Liturgy of the Word is the reading of the Gospel. Because the Gospels tell of the life, ministry, and preaching of Christ, it receives several special signs of honor and reverence. The gathered assembly stands to hear the Gospel and it is introduced by an acclamation of praise. Apart from Lent, that acclamation is "Alleluia," derived from a Hebrew phrase meaning "Praise the Lord!" A deacon (or, if no deacon is present, a priest) reads the Gospel. After the Scripture readings, the celebrant preaches the homily. In the homily, the preacher focuses on the Scripture texts or some other texts from the liturgy, drawing from them lessons that may help us to live better lives, more faithful to Christ's call to grow in holiness. In many Masses, the Profession of Faith then follows the homily, either the Nicene or Apostles' Creed. The Nicene Creed is a statement of faith dating from the fourth century, while the Apostles' Creed is the ancient baptismal creed of the Church in Rome. If baptismal promises are renewed, from a formula based on the Apostles' Creed, this takes the place of the Creed. The Liturgy of the Word concludes with the Universal Prayer, also called the Prayer of the Faithful. The gathered assembly intercedes with God on behalf of the Church, the world, and themselves, entrusting their needs to the faithful and loving God. ADDITIONAL INFORMATION ON THE LITURGY OF THE WORD Hearing the Word of God Proclamation of the Gospel by the Laity The Lector at Mass Universal Prayer (Prayer of the Faithful) LITURGY OF THE EUCHARIST The Liturgy of the Eucharist begins with the preparation of the gifts and the altar. As the ministers prepare the altar, representatives of the people bring forward the bread and wine that will become the Body and Blood of Christ. The celebrant blesses and praises God for these gifts and places them on the altar, the place of the Eucharistic sacrifice. In addition to the bread and wine, monetary gifts for the support of the Church and the care of the poor may be brought forward. The Prayer over the Offerings concludes this preparation and disposes all for the Eucharistic Prayer. Eucharistic Prayer The Eucharistic Prayer is the heart of the Liturgy of the Eucharist. In this prayer, the celebrant acts in the person of Christ as head of his body, the Church. He gathers not only the bread and the wine, but the substance of our lives and joins them to Christ's perfect sacrifice, offering them to the Father. The introductory dialogue, establishes that this prayer is the prayer of the baptized and ordained, is offered in the presence of God, and has thanksgiving as its central focus. Following this dialogue, the celebrant begins the Preface. The Eucharistic Prayers make clear that these prayers are offered, not to Christ, but to the Father. It is worship offered to the Father by Christ as it was at the moment of his passion, death and resurrection, but now it is offered through the priest acting in the person of Christ, and it is offered as well by all of the baptized, who are part of Christ's Body, the Church. This is the action of Christ's Body, the Church at Mass. The priest offers the Eucharistic Prayer in the first person plural, for example, "Therefore, O Lord, we humbly implore you…" This "we" signifies that all the baptized present at the Eucharistic celebration make the sacrificial offering in union with Christ, and pray the Eucharistic Prayer in union with him. And what is most important, we do not offer Christ alone; we are called to offer ourselves, our lives, our individual efforts to grow more like Christ and our efforts as a community of believers to spread God's Word and to serve God's people, to the Father in union with Christ through the hands of the priest. Most wonderful of all, although our offering is in itself imperfect, joined with the offering of Christ it becomes perfect praise and thanksgiving to the Father. The General Instruction of the Roman Missal (no. 79) provides the following summary of the Eucharistic Prayer: The main elements of which the Eucharistic Prayer consists may be distinguished from one another in this way: a) The thanksgiving (expressed especially in the Preface), in which the Priest, in the name of the whole of the holy people, glorifies God the Father and gives thanks to him for the whole work of salvation or for some particular aspect of it, according to the varying day, festivity, or time of year. b) The acclamation, by which the whole congregation, joining with the heavenly powers, sings the Sanctus (Holy, Holy, Holy). This acclamation, which constitutes part of the Eucharistic Prayer itself, is pronounced by all the people with the Priest. c) The epiclesis, in which, by means of particular invocations, the Church implores the power of the Holy Spirit that the gifts offered by human hands be consecrated, that is, become Christ's Body and Blood, and that the unblemished sacrificial Victim to be consumed in Communion may be for the salvation of those who will partake of it. d) The Institution narrative and Consecration, by which, by means of the words and actions of Christ, that Sacrifice is effected which Christ himself instituted during the Last Supper, when he offered his Body and Blood under the species of bread and wine, gave them to the Apostles to eat and drink, and leaving with the latter the command to perpetuate this same mystery. e) The anamnesis, by which the Church, fulfilling the command that she received from Christ the Lord through the Apostles, celebrates the memorial of Christ, recalling especially his blessed Passion, glorious Resurrection, and Ascension into heaven. f) The oblation, by which, in this very memorial, the Church, in particular that gathered here and now, offers the unblemished sacrificial Victim in the Holy Spirit to the Father. The Church's intention, indeed, is that the faithful not only offer this unblemished sacrificial Victim but also learn to offer their very selves,and so day by day to be brought, through the mediation of Christ, into unity with God and with each other, so that God may at last be all in all.
